Sound chip recordings... How is it done?

Sound chip (DSP) recordings... How is it done?

Pardon my ignorance and naivety, but....

A group of model railroaders would like to customize/personalize the train
sound announcements that have been recorded on the sound chip on their
locomotives and railcars.

Is there a website that, in layman's language, explains how sound effects
are "recorded" on a sound chip?  ... and, how one would/could "re-record"
or "re-program" a sound chip with the particular sounds that are
appropriate for ones use?

What type of equipment is necessary for programming a sound chip?

Are there companies that will "customize" a sound chip for your particular
needs?

Thanks for any and all information you can pass along   .... to us
novices!!

What does this mean? That the horn sounds differently for each train? That the PA announcements on the stations sound differently?

Maybe there is, but probably not from a technical point of view. As a first suggestion, try musician's web sites and see if you can find explanations of sound effects. You are looking for the same sort of technology but with a different application. Rune

You'll need a ROM of some sort and a D/A convertor + amp and a speaker (a cheap one that they use in toys is fine). Record the sound effects 8 bits sampled at 11.25kHz on a PC and then write to ROM. There maybe a kit you can buy somewhere. M.P -- Posted via a free Usenet account from http://www.teranews.com
